Rogers v Bellei-
“It is not too much to say, therefore, that Congress at that time [when Rev.Stat. § 1993 was under consideration] attached more importance to actual residence in the United States as indicating a basis for citizenship than it did to descent from those who had been born citizens of the colonies or of the states before the Constitution. As said by Mr. Fish, when Secretary of State, to Minister Washburn, June 28, 1873, in speaking of this very proviso,”
“the heritable blood of citizenship was thus associated unmistakably with residence within the country which was thus recognized as essential to full citizenship.”
“Foreign Relations of the United States, Pt. 1, 1873, p. 259.”
